PIR sensor
All Ajax motion detectors use PIR sensors by Excelitas Technologies, a field-leading American manufacturer specialising in designing and producing optronic components since 1931. Ajax Systems constantly proves the sensor’s Superior quality at the production stage: we test 100% of manufactured devices. Wrapped in Ajax technologies, it brings the utmost accuracy of intrusion detection.
Special lens
The pattern of the Fresnel lens sections is designed to differentiate between the IR diagrams of a human, pet, and thermal noise. Large lens sections capture radiation at an adult’s head and torso level. Smaller sections make the diagram more detailed. The lens provides the detector with accurate information about the thermal object in the detection zone and the nature of its movement.
Thermal interferences filter
We processed thousands of thermal patterns caused by humans, pets, and the environment to develop the SmartDetect software algorithm. In armed mode, the detector constantly analyses the thermal diagram from the PIR sensor, including the IR radiation intensity, thermal spot size, movement speed, time spent in the detection zone, and other parameters. The algorithm identifies false alarm markers instantly and with high accuracy. As a result, the detector accurately responds to human movement without false alarms.

Temperature compensation
Temperature compensation is a software mechanism that maintains the thermal diagram’s contrast even if the ambient temperature is close to the temperature of the human body. With each ambient temperature measurement, the detector corrects the PIR sensor data according to the coefficient table stored in its memory. The detector is effective over the entire operating temperature range.
Sensitivity level
The detector can adapt to the conditions of a particular facility, considering possible thermal interference or pets. The sensitivity setting changes the set of markers by which false alarms are filtered. Low sensitivity makes the detector less likely to respond to an active pet. With high sensitivity, an alarm is raised whenever there is any movement in the detection area.
Professional installation
With the correct installation at the height of 2.4 m and lens direction perpendicular to an alleged intrusion path, the detector provides an accurate thermal diagram and pet immunity. It instantly responds to a real threat, minimising false alarms caused by pets weighing up to 20 kg and below 50 cm in height.
Stable and reliable performance
MotionProtect U Jeweller is equipped with a high-quality battery from proven manufacturers only. In addition to real-time testing during battery production, Ajax Systems inspects every unit to ensure the accuracy of the batteries’ characteristics. The battery provides stable performance at temperatures from –10 °C to +40 °С.

Jeweller
Unique wireless technology
Jeweller is Ajax’s proprietary radio protocol for secure two-way communication. It provides block encryption and device authentication during each communication session with an Ajax hub or radio signal range extender. Jeweller prevents sabotage, spoofing, and data theft.
Up to 1,700 m of communication range in an open space
Data encryption
Notification of jamming and connection loss
Automatic power adjustment
Scaled and comprehensive
ReX 2 Jeweller range extender boosts the radio range of all Ajax devices via Jeweller and ensures stable communication through steel and concrete via Ethernet using the wire as the additional communication channel. Up to 5 range extenders can operate within one Ajax system to expand the network twice as big, covering multistorey buildings with underground parking and basements.
Up to 5 range extenders within one system
Ethernet as an alternative communication channel
System supervision
The device performs automatic self-diagnosis and reports its status to the hub. Essential parameters, including tamper, communication, power supply, and sensor statuses, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for ARCs, security companies, and users. In case of any malfunction or communication failure, an engineer is informed immediately to provide necessary services.
Automatic device self-diagnosis with status report
Regular polling to display the current devices’ state on apps
Instant maintenance notifications
Sabotage resistance
Effortless installation and setup
MotionProtect U Jeweller is ready to operate straight out of the box. Using the SmartBracket panel, an installer can effortlessly mount the device on the wall or in the corner, eliminating the need to disassemble the enclosure. Ajax apps help quickly make the device a part of the ecosystem: simply pair the device with the hub by scanning the QR code. It can always be reconfigured remotely without the need for on-site visits.
